Specify device about hello_tf_c_api

Hi @ttdd11
Try something like

TF_OperationDescription* desc = TF_NewOperation(graph, op_type, op_name);
TF_SetDevice(desc, "/gpu:0");

I have not tried these operations, but I think you can search for information on these functions, it looks like they do what you need

@Neargye Okay i tried this. Here is my code:

TF_Operation* op;
std::size_t pos = 0;

while ((op = TF_GraphNextOperation(graph, &pos)) != nullptr) {
	const char* name = TF_OperationName(op);
	QString strName = QString(name);
	TF_OperationDescription* desc = TF_NewOperation(graph, TF_OperationOpType(op), TF_OperationName(op));
	TF_SetDevice(desc, "/gpu:0");

Has no effect of the device being used.

Unfortunately, I did not try to run on GPU using this function TF_ImportGraphDefOptionsSetDefaultDevice
